Oregon fire is the largest burning in the US. Officials warn an impending storm could exacerbate it

A wildfire in Oregon is now the largest active blaze in the U.S., sending smoke into neighboring states and creating air quality issues across the west. Crews are now preparing for another storm bringing potential lightning and flash floods. The fire has rapidly expanded due to high temperatures and dry conditions, increasing tens of thousands of acres since Sunday, July 21. Over 60 significant fires are burning in Oregon and Washington, with lightning strikes from thunderstorms igniting new fires in dry vegetation.
